Hot aisle containment consists of a physical barrier that guides hot exhaust airflow back to the AC return. Essentially creating a room within the aisle, the system helps keep hot and cold air separated to make existing air conditioning systems in data center and edge-of-network.

Aisle containment separates hot and cold air for efficient cooling, better temperature control, improved equipment performance and energy savings Installation is simple and cost-effective, with manageable kits and included hardware, requiring no contractor or HVAC specialistAisle containment separates hot and cold air for efficient cooling, better temperature control, improved equipment performance and energy savings Installation is simple and cost-effective, with manageable kits and included hardware, requiring no contractor or HVAC specialistThe cold aisle layout is the most common starting point in data center design. Server racks are arranged in rows so that the fronts of the racks face each other, forming a corridor known as the cold aisle. Cold air is delivered into this aisle through: Servers pull this cold air into their front. Cold aisle containment creates an enclosed corridor in front of server cabinets, ensuring that the coldest air goes directly into equipment intakes. On the other hand, the hot exhaust air rebels, determined to mix in and cause chaos.

In 2024, Worthington Armstrong Venture (WAVE), a joint venture between Armstrong World Industries, Inc. , acquired all of the assets of Data Center Resources, LLC (DCR) related to the design and manufacture of customizable, modular aisle. Our aisle containment systems are designed to optimize energy use and enhance airflow management in data centers, both new and existing. Pre-assembled frame with slide-locks for easy installation, airtight gaskets, ergonomic handles, and panel options in clear or multiwall. Essentially creating a room within the aisle, the system helps keep hot and cold air separated to make existing air conditioning systems in data center and edge-of-network.

If you're a typical user deploying or upgrading a mid-density (5–12 kW/rack) data center with raised-floor cooling and standard CRAC/CRAH units, cold aisle containment is the faster, lower-risk starting point—and hot aisle containment becomes worth serious consideration only when. Hot aisle and cold aisle containment are foundational concepts in data center design.
